Yeah did the t shape but can't get it to stand straight so will just have to figure a way to support it. Thanks. Basically I have two air stones and by the time the are 8 inches or less tall it all becomes a DWC anyway. If the roots are hanging in the water do you really need the sprayers on anymore???? thanks... Like I said two big air stones....one tub, no drain just it and itself. Tried the tub on bottome thing but to big a hassle so they grow big in the one and then into the fence posts for the bloom. One last question. Useing bonicare nutes and it clogs, want to switch to GH grow bloom and micro for hard water, do I need the micro? and is it ok to switch from bonicare after when I put them into bloom. If my big tubes get clogged late in flower it is a royal pain in the butt. And also looking to remove my pvc that is in the 6' pvc fence bloom tubes, 50 holes and putting the feed lines outside and running little plastic or rubber? tubes to top holes inbetween the net pots but don't know how to get them into the feed pvc and or the tubes without getting leaks at the insertion points?????
